Check out latest 3DObject release for a bugfix

Yes, this is not meant for tiled background object. It is a 'light' replacement for tiled background.

Yes, do not use with changing color or opacity, instead use the parameters on the effect (the object properties will cause the effect to not be the first effect.)

Do you mean the 3DObject lights controlled by ACEs in 3DObject (it is not an effect) or something else? A screen shot of what settings you are talking about would help.

If you are looking at light layer, effect it does not handle world position lights, only  relative to view and no normal or phong support.

Are you using it with 3DShapes or 3DObjects?

 if used with 3DObjects, you can look at having normals being included with your glb model. Then enable phong lighting, which smooths out lighting

That is a new one! Can you send a test project?

Check that the renderer is webgl2 in the project setting, only webgl2 now is supported for the effect, I will update the webpage and remove older versions.

I suggest adding 3dobject (free addon) to your project. It will handle what main.js previously did, and you can leave out main.js.

Light types

Just use the last version (2.7.0).

if you use it with 3DObject you should not include the main.js file.

You can look at some of the sample projects to see how it works.

This addon does NOT draw 3D Models, it is only an effect.

It would be great if only the latest versions on one download page and older versions on a different download page. 
The documentation seems outdated.  It says This effect requires the main.js file from the example project to be included - yet in the comments here it says it is not required.. which is it? Also - there is no documentation about the different light types - what does each one do? 

Not right now. There is a tile parameter towards the end, but it is just for flipping and tiling a single 'seamless' texture.

Try using the latest versions of both frag light and 3D Object _and_ remove the main.js script from the project. If that doesn't work, let me know.

I just tried:3DObjectFragLight-8.c3p and FragLightTrain.c3pand they worked for me. Make sure you are using the latest version of the effects and 3dobject addon. When using the latest 3DObject in 3DObjectFragLight-8.c3p, remove the main.js script from the project (the addon does the change itself.)

If you still see an error on loading, Hit 'F12' to bring up dev console and take a snapshot of the error and post it here.

Did you install the latest 3D effect addon?

This does per pixel shading, however the pixel normal is calculated from the tangent of nearby pixels, so it is effectively a plane. The difference from 3Object lighting is that the light attenuation can vary across the face of a polygon. Additionally spotlight edges can vary across the face of a polygon. Finally, you can enable procedural normals based on diffuse texture which can further vary the normal and light calculation.

I am also experimenting with adding normal map support to this effect with 3DObject, it is not yet available, but if the experiment works out, I'll add it as an option.

This depends on the requests I have made for SDK V2, waiting for a response from Scirra. In the past requests have takes months to years to get implemented. If they implement the requests, main.js will no longer be needed.

Scirra has said the current SDK will be supported at least for two more years (through C3 SDK V1 LTS), which is what is used with the main.js file.

What do you mean? Can you provide more details?

I would think it would on any modern android platform, but have not tried it.

Thank you!

With this version (early in development), you do not set the position/color in js code. You use the effect parameters. You can set them as properties in the editor or change them at runtime with events with the set effect parameter action. The JS code is now only to patch the vertex shader to enable the effect/addon.
